lecture 14 part 2

Question 1

xwhat is the first part of aerobic respiration

Answer 1

glycolysis

Question 2

what type of pathway is glycolysis

Answer 2

sugar splitting pathway

Question 3

where does glycolysis occur

Answer 3

cytosol

Question 4

how many biochemical reactions occur in glycolysis

Answer 4

10

Question 5

does glycolysis require O2

Answer 5

no (aeorbic process)

Question 6

what does glycolysis require

Answer 6

ATP

Question 7

what does glycolysis produce

Answer 7

4 ATP and 2 NADH

Question 8

in the glycolysis energy investment phase _ carbon moleqs go to _ carbon olecules

Answer 8

6 -> 3

Question 9

how many ATP are hydrolyzed per glucose during energy investment phase

Answer 9

2
-phosphate groups are trasnferred to sugar molecules

Question 10

phosphate groups inc/dec the free enrgy of the sugar molecule during enegry investment phase

Answer 10

increase

Question 11

during steps 1 & 3 (key regulatory steps) what do cellular conditions do during energy investment phase

Answer 11

speed up or slow down enzymatic rates at these steps (save glucose rarher than use it when the cell has plenty of ATP)

Question 12

what happens during the energy payoff phase of glycolysis

Answer 12

each 3 carbon sugars generate 1 NADH and 2 ATP
and get two 3 carbon pyruvate moleq per glucose moleq

Question 13

what is recovered during energy payoff phase

Answer 13

2 ATP from earlier energy investment phase

Question 14

what does NADH carry

Answer 14

high energy electron, the electron will be donated to the ETC

Question 15

substrate level phosphorylation

Answer 15

transfer of a phosphate group from an organic moleq (substrate to ADP to make ATP)
